Class intended to support codegen of all kind of the reduction clauses. More...

#include "/home/buildbot/as-worker-4/publish-doxygen-docs/llvm-project/clang/lib/CodeGen/CGOpenMPRuntime.h"

  ReductionCodeGen (ArrayRef< const Expr * > Shareds, ArrayRef< const Expr * > Origs, ArrayRef< const Expr * > Privates, ArrayRef< const Expr * > ReductionOps)   void  emitSharedOrigLValue (CodeGenFunction &CGF, unsigned N)   Emits lvalue for the shared and original reduction item.
  void  emitAggregateType (CodeGenFunction &CGF, unsigned N)   Emits the code for the variable-modified type, if required.
  void  emitAggregateType (CodeGenFunction &CGF, unsigned N, llvm::Value *Size)   Emits the code for the variable-modified type, if required.
  void  emitInitialization (CodeGenFunction &CGF, unsigned N, Address PrivateAddr, Address SharedAddr, llvm::function_ref< bool(CodeGenFunction &)> DefaultInit)   Performs initialization of the private copy for the reduction item.
  bool  needCleanups (unsigned N)   Returns true if the private copy requires cleanups.
  void  emitCleanups (CodeGenFunction &CGF, unsigned N, Address PrivateAddr)   Emits cleanup code for the reduction item.
  Address  adjustPrivateAddress (CodeGenFunction &CGF, unsigned N, Address PrivateAddr)   Adjusts PrivatedAddr for using instead of the original variable address in normal operations.
  LValue  getSharedLValue (unsigned N) const   Returns LValue for the reduction item.
  LValue  getOrigLValue (unsigned N) const   Returns LValue for the original reduction item.
  std::pair< llvm::Value *, llvm::Value * >  getSizes (unsigned N) const   Returns the size of the reduction item (in chars and total number of elements in the item), or nullptr, if the size is a constant.
  const VarDecl *  getBaseDecl (unsigned N) const   Returns the base declaration of the reduction item.
  const Expr *  getRefExpr (unsigned N) const   Returns the base declaration of the reduction item.
  bool  usesReductionInitializer (unsigned N) const   Returns true if the initialization of the reduction item uses initializer from declare reduction construct.
  QualType  getPrivateType (unsigned N) const   Return the type of the private item.
